Y MULTIPLE VALVE.

i Application led February 18, 1924. Serial No. 693,541.

To all whom t may 00a-cem:

Be it known that l, FRANK GEizDnoN, a citizen of the United States, residing in the city of Detroit, county of lVayne, State of Michigan, have invented certain new and useful Improvements in a Multiple Valve, and declare the following to be full, clear, and exact description of the same, such as will enable others skilled in the art to which it' pertains to make and use the same, refer- 'encebeing had to the accompanying drawings, which form a part ot these .specifica- VThe object ot my invention is to provide a valve having multiple inlet pipes, which can f be operated by a single valve stem- A further object is to produce a valve that can be turned to any single inlet pipe desired, and without .opening the other inlet pipes.

lt is Otten desired to conduct liquids -from various tanks, oi* compartments, into a single tank, as t'or compounding various ingredients, and my multiple valve is adapted to i that purpose,also for changing the flow of various liquids into a. 'common outlet pipe.

A still further object is to provide a valve j that is simple in construction, easily and Aetlicien'tly operated and can 'be manufactured at a low cost.

V struction of the valve.

Fig. 5, is a section view --AA-- in Fig. 1,

Vshowing the position of the valve port as it is opened into one of the inlet pipes.

Fig. 6, is a modilied form ot the two port Vvalve havingthe port openings at one side of the valve so that a slight movement of Vthe valve stem will close either one ot the ports and allow the other to continue, or

'close both ports.

I will now describe more fully the detailed construction of my valve, referring to the drawings and the marks thereon.

The general construction of my multiple connection valve consists of a cast valve casing provided with a. tapered valve chamber extending through the body of the casting.` and inlet pipe connections projecting from the side ot the casting, and at right angles thereto. The inlet pipe connections open directly into the valve chamber, same being closed by a tapered plug valve fitted into the chamber, but which is free to turn therein in such a manner that the port in the valve plug may be brought into the opening of any of the inlet connection openings.

The valve casting may be made of any suitable material, but preferably of brass, and isformed with a hollow body casting -1'-, having the inlet pipes -2-- projecting from the sides thereof. The hollow conical opening inside the body casting --1-- is turned true and smooth to receive the tapered valve plug f3- and forming a tight joint therewith. The inlet pipes --2- lead directly into the valve chamber, and are threaded on the outer end thereof to receive pipe connections leading from said valve. The tapered valve plug -3- is made also with a true turned surface and fits closely the chamber walls in the body casting -l-. The taper valve plug is also provided with a chamber 4.- which is open at the lower end of the plug stem, In the side of the taper valve -3-, anc leading into the plug chamber t1 is a valve port -5-, completing a passage from the inlet pipe connection, into the valve chamber flfrom whence it passes from the valve. The taper plug valve n-3-- is provided with a cylindrical valve stem -G-, tiXedly attached thereto. To the valve stem --6- is` attached a valve handle T, 'forming a means for turning the. valve plug -3- within the valve chamber in the casing -l-. The top end of the valve casing --lis threaded to receive an adjusting cap --8- which lits over the valve stem -6-, and also retains thereunder an adjusting valve spring --9-, which presses downward on the tapered plug valve -8-, holding same firmly in position in the valve chamber. By varying the position 0f the cap -8- on the casing -1-, the tension of the spring -9- may also be varied to change the pressure rising.; a flpw fnquia ifeaaiag enough intake pipe.
